Raman was a great lover of music. He used to say: I should live long, […]Continue reading…

Ok, now I want to share a minor tip about how to write cm-1 very fast and very simple (in Microsoft Word). First of all discussion about this shortcut, I want to be clear: ctrl+c -> ctrl+v. This is commonly used shortcut, but in some cases (for whatever reason) we can not use. What to […]Continue reading…

Advantages of Raman Spectroscopy many organic and inorganic materials are suitable for Raman analysis. These can be solids, liquids, polymers or vapors. no sample preparation needed. not interfered by water. non-destructive. highly specific like a chemical fingerprint of a material. Raman spectra are acquired quickly within seconds. samples can be analyzed through glass or a […]Continue reading…

Number and symmetry of vibrations With any molecule, the energy can be divided into translational energy, vibrational energy and rotational energy. Translational energy can be described in terms of three vectors 90° to each other and so has three degrees of freedom. Rotational energy for most molecules can also be described in terms of three […]Continue reading…
